Ozone on Kubernetes

Requirements

  • Working kubernetes cluster (LoadBalancer, PersistentVolume are not required)
  • kubectl

As the apache/ozone docker images are available from the dockerhub the deployment process is very similar to Minikube deployment. The only big difference is that we have dedicated set of k8s files for hosted clusters (for example we can use one datanode per host) Deploy to kubernetes

kubernetes/examples folder of the ozone distribution contains kubernetes deployment resource files for multiple use cases.

To deploy to a hosted cluster use the ozone subdirectory:

  1. cd kubernetes/examples/ozone
  2. kubectl apply -f .

And you can check the results with

  1. kubectl get pod
  2. Access the services

Now you can access any of the services. By default the services are not published but you can access them with port-forward rules.

  1. kubectl port-forward s3g-0 9878:9878
  2. kubectl port-forward scm-0 9876:9876
